BUILDING CONSTRUCTION,

Application filed November 17!, 19W. Berlal lt'c. 2333M.

This invention relatesto means for scour ing to supporting beams sheet metal founda tions having hollow ribs extending from one side thereof. More particularly, the invention consists in providing clamping and se curing n eans for sheet metal constructions of the general type shown in the patent granted jointly to Harry Gillett and myself on February 3,1926, No. 1,574,586.

,lt is the general purpose and object of the invention to provide a clamping device which is particularly adapted for ready and corn venient application to the ribs of sheet metal foundations and which will provide effective means for supporting the foundations from purlins or other beams.

T realise the foregoing objects, and other and more limited objects which will appear hereinattcr, inand through the construction and arr ngement parts shown in the drawing, wherein l 'i represents a detail in transverse section trough one form of metal foundation showing; the manner in which the same clamped or applied to a n through an I-heam and the sheet metal ndation thereabove, showing the manner in which the latter is secured to said beam; 3 a detail in plan of one of my clamping devices, showing the manner in which. the same is applied to a joist or purlin; a a detail in transverse section showing the positions of: the bottom of a. rib and of the clamp ing device prior to the final clamping oper atron; Fig", a view similar to Fig. t showing the clamping device in its final and openative position with relation to the rib; Fig. 6 a view, similar to Fig. 1, showing a metal foundation having a diiferent form of ribs projecting therefrom; and Figspi' and 8 are details in transverse section of such modification, the said views being similar to Figs. 4 and 5 respectively.

Descri ing by reference characters the parts shown in Fi s. 1 to 5 inclusive, 1 denotes a flat metal s set of which the foundation is formed, the same being rovided with hollow triangular ribs rojectin from one side thereof, the sides 0 the ribs eing indicated at 2 and the bottoms at 3, there being slots 4 between the tops of the ribs and the metal sheets.

5 denotes the web and 6 the flanges of a beam on which the aforesaid sheet is to be supported. The beam may be of any of the ordinary commercial sha es, the one shown herein being an I beam. or the purpose of securing the sheet, either to an I beam such as shown, or to the top flange of a channel beam, I provide a sheet metal clamp, the said clamp having an upwardly projecting base 7 and slotted longitudinal extensions One of such extensions is bent to form a. hook, indicated at 8, which hook is so shaped as to engage the edge of one of the flanges 6. Where the metal foundation is to be used for rooting purposes, the book 8 will engage the upper edge of the flan go of the beam or purlin. The opposite extension, comprising the branches 9, is bent around the edge of the other flange 6, where l. beams are employed, the positions of the parts before bending being; shown in dot-and-dash lines on 2 and The hoolt formed by bending he eatension 9 is indicated at 10. Where the clamps are used with channel beams, the errtensions 9 are bent downwardly along the webs of such beams.

it will be noted that the ends of the entension'sd and are joined, as shown at d and i), This prevents the ends from separating or spreading during the operation of flattening the base l, under conditions to be en lained hereinafter.

eference has been made hereinbe'fore to the upwardly projecting base 7. As will appear from Fig. 4, this base is projected up wardly or arched from each side thereof; and from each side there projects a flange 7, each flange .7 making with the portion of the bottom adjacent thereto an angle slightly less than the angle between the sides 2 and the bottom 3 of the rib which is to be received within such clamp. The over-all width of the bottom 7 is equal to the width of the base 3 of the rib which it receives.

With the parts constructed and arranged as described, the clamps will be applied to beams or purlins such as shown herein by slipping the hooks over the up or edges of the flanges 6 thereof (Where t e beams or purlins are used for roof construction) and ending the lower ends around and beneath the bottoms of the flanges. The clamps having been so applied to the beams or urlins and in proper spaced relation to receive the ribs therewithin, the metal foundation will be applied, positioning the ribs between the side thereof.

bit

flanges of the clamps, as shown in Fig. 4. After having'been so positioned, a suitable tool (indicated in dot-and-dash lines at 11 on Fig. 4) is introduced into each slot 4, the bottom of which tool engages the bottom 3 of the rib above the center of the arch 7. Then by hammering or otherwise exerting downward pressure through the tool upon the bottom of the rib and upon the arch 7 the base of the clamp will be straightened, as shown in Fig. 4, and, because of the fact that the angle between each side 'i and theportion of the base adjacent'thereto is less than the angle be tween each side 2 and the bottom 3, the flange 7 will firmly clamp the sides of the ribs.

In the modification shown in Figs. 6, 7

and 8, the metal sheet- 12 is provided with inverted T-shaped ribs formed therewith and projecting from one side thereof, the shank" of such a T being shown at 13 and the base at 14.

The clips which I employ for securing ribs of this character to a beam or purlin are of the same character as those shown in the preceding views.

As will appear from the drawing, the arch or upward projection of the base 7 and the inclination of the side flanges 7 a are such that, when the ribs 13, 14 are pressed downwardly by a .suitable tool within the clamps, the

straightening out of the arched bases 7 causes the flanged sides 7 to engage the sides of the bases 14 of the ribs inserted therebetween with the upper ends of the sides extending above 'such bases. The side flanges 7 are shown as longer than need be employed for engaging the bases 14 of the ribs 13; .but, by using such flanges, only one style of clamping device need be kept in stock for both types of ribs shown herein. I

By the construction of clamp shown and described herein, I am enabled to apply the same very quickly and conveniently to the purlins or other oists by which the ribs of-the sheet metal foundation are to be supported; to insert the ribs within the seats provided therefor in such clamp; and, b a simple operation, to firmly secure the ri s in the seats formed by the clamps.

Having thus described my invention, what I claim is 1. A, sheet metal clamping device for securing to a beam a sheet havlng a hollow triangular rib projecting therefrom, the said clamping device having means whereby it may be applied to-a beam and provided with an upwardly projecting base having upwardly projecting flanges at each side thereof, the angle between each flange and the adjacent portion of the upwardly projecting base being slightly less than the angle formed between the bottom and each side of such rib, whereby the rib may be inserted between suchuflanges and the bottom of the rib and the base of the clamping member pressed downwardly thereby to spring the flanges inwardly into engagement with the sides of such rib.
